Abstract

A vehicle-mounted unit (20) sends (at S103) an assignment request for radio resources to a road-side unit (10B). This road-side unit (10B) assigns (at S104 and S105), when it receives that assignment request, road-vehicle resources or radio resources for road-vehicle communications with the vehicle-mounted unit (20) and vehicle-vehicle resources or radio resources for vehicle-vehicle communications between the vehicle-mounted units (20), and sends (at S106) the assignment information to the vehicle-mounted unit (20). The vehicle-mounted set (20) performs (at S110 and S111) the road-vehicle communications with the road-side unit (10B) by using the road-vehicle resources recognized by the assignment information received from the road-side unit (10B), and performs (at S112 to S115) the vehicle-vehicle communications with another vehicle-mounted set (20) by using the vehicle-vehicle resources discriminated with that assignment information. As a result, the road-vehicle communications and the vehicle-vehicle communications of high utilizing efficiencies of the radio resources can be realized while avoiding the 'hidden terminal problem'.
